Geliang Tang b6e074e171 selftests: mptcp: add infinite map testcase
Add the single subflow test case for MP_FAIL, to test the infinite
mapping case. Use the test_linkfail value to make 128KB test files.

Add a new function reset_with_fail(), in it use 'iptables' and 'tc
action pedit' rules to produce the bit flips to trigger the checksum
failures. Set validate_checksum to enable checksums for the MP_FAIL
tests without passing the '-C' argument. Set check_invert flag to
enable the invert bytes check for the output data in check_transfer().
Instead of the file mismatch error, this test prints out the inverted
bytes.

Add a new function pedit_action_pkts() to get the numbers of the packets
edited by the tc pedit actions. Print this numbers to the output.

Also add the needed kernel configures in the selftests config file.

Vladimir Oltean 07c8a2dd69 selftests: drivers: dsa: add a subset of forwarding selftests
This adds an initial subset of forwarding selftests which I considered
to be relevant for DSA drivers, along with a forwarding.config that
makes it easier to run them (disables veth pair creation, makes sure MAC
addresses are unique and stable).

The intention is to request driver writers to run these selftests during
review and make sure that the tests pass, or at least that the problems
are known.

Vladimir Oltean 90b9566aa5 selftests: forwarding: add a test for local_termination.sh
This tests the capability of switch ports to filter out undesired
traffic. Different drivers are expected to have different capabilities
here (so some may fail and some may pass), yet the test still has some
value, for example to check for regressions.

There are 2 kinds of failures, one is when a packet which should have
been accepted isn't (and that should be fixed), and the other "failure"
(as reported by the test) is when a packet could have been filtered out
(for being unnecessary) yet it was received.

The bridge driver fares particularly badly at this test:

TEST: br0: Unicast IPv4 to primary MAC address                      [ OK ]
TEST: br0: Unicast IPv4 to macvlan MAC address                      [ OK ]
TEST: br0: Unicast IPv4 to unknown MAC address                      [FAIL]
        reception succeeded, but should have failed
TEST: br0: Unicast IPv4 to unknown MAC address, promisc             [ OK ]
TEST: br0: Unicast IPv4 to unknown MAC address, allmulti            [FAIL]
        reception succeeded, but should have failed
TEST: br0: Multicast IPv4 to joined group                           [ OK ]
TEST: br0: Multicast IPv4 to unknown group                          [FAIL]
        reception succeeded, but should have failed
TEST: br0: Multicast IPv4 to unknown group, promisc                 [ OK ]
TEST: br0: Multicast IPv4 to unknown group, allmulti                [ OK ]
TEST: br0: Multicast IPv6 to joined group                           [ OK ]
TEST: br0: Multicast IPv6 to unknown group                          [FAIL]
        reception succeeded, but should have failed
TEST: br0: Multicast IPv6 to unknown group, promisc                 [ OK ]
TEST: br0: Multicast IPv6 to unknown group, allmulti                [ OK ]

mainly because it does not implement IFF_UNICAST_FLT. Yet I still think
having the test (with the failures) is useful in case somebody wants to
tackle that problem in the future, to make an easy before-and-after
comparison.

Bombard a standalone switch port with various kinds of traffic to ensure
it is really standalone and doesn't leak packets to other switch ports.
Also check for switch ports in different bridges, and switch ports in a
VLAN-aware bridge but having different pvids. No forwarding should take
place in either case.

Vladimir Oltean a5114df6c6 selftests: forwarding: add helper for retrieving IPv6 link-local address of interface
Pinging an IPv6 link-local multicast address selects the link-local
unicast address of the interface as source, and we'd like to monitor for
that in tcpdump.

Add a helper to the forwarding library which retrieves the link-local
IPv6 address of an interface, to make that task easier.

Extend the forwarding library with calls to some small C programs which
join an IP multicast group and send some packets to it. Both IPv4 and
IPv6 groups are supported. Use cases range from testing IGMP/MLD
snooping, to RX filtering, to multicast routing.

Testing multicast traffic using msend/mreceive is intended to be done
using tcpdump.

Extend tcpdump_start() & C:o to handle multiple instances.  Useful when
observing bridge operation, e.g., unicast learning/flooding, and any
case of multicast distribution (to these ports but not that one ...).

This means the interface argument is now a mandatory argument to all
tcpdump_*() functions, hence the changes to the ocelot flower test.

Vladimir Oltean b343734ee2 selftests: forwarding: add option to run tests with stable MAC addresses
By default, DSA switch ports inherit their MAC address from the DSA
master.

This works well for practical situations, but some selftests like
bridge_vlan_unaware.sh loop back 2 standalone DSA ports with 2 bridged
DSA ports, and require the bridge to forward packets between the
standalone ports.

Due to the bridge seeing that the MAC DA it needs to forward is present
as a local FDB entry (it coincides with the MAC address of the bridge
ports), the test packets are not forwarded, but terminated locally on
br0. In turn, this makes the ping and ping6 tests fail.

Address this by introducing an option to have stable MAC addresses.
When mac_addr_prepare is called, the current addresses of the netifs are
saved and replaced with 00:01:02:03:04:${netif number}. Then when
mac_addr_restore is called at the end of the test, the original MAC
addresses are restored. This ensures that the MAC addresses are unique,
which makes the test pass even for DSA ports.

The usage model is for the behavior to be opt-in via STABLE_MAC_ADDRS,
which DSA should set to true, all others behave as before. By hooking
the calls to mac_addr_prepare and mac_addr_restore within the forwarding
lib itself, we do not need to patch each individual selftest, the only
requirement is that pre_cleanup is called.

Ido Schimmel 5e6242151d selftests: mlxsw: vxlan_flooding_ipv6: Prevent flooding of unwanted packets
The test verifies that packets are correctly flooded by the bridge and
the VXLAN device by matching on the encapsulated packets at the other
end. However, if packets other than those generated by the test also
ingress the bridge (e.g., MLD packets), they will be flooded as well and
interfere with the expected count.

Make the test more robust by making sure that only the packets generated
by the test can ingress the bridge. Drop all the rest using tc filters
on the egress of 'br0' and 'h1'.

In the software data path, the problem can be solved by matching on the
inner destination MAC or dropping unwanted packets at the egress of the
VXLAN device, but this is not currently supported by mlxsw.
